Welcome to DARTS/MAXI

MAXI (Monitor of All-sky X-ray Image) is mounted on the Japanese Experimental Module (KIBO) of the International Space Station.
MAXI has been developed in collaboration of JAXA and RIKEN.
MAXI has not only a wide field of view, but also a higher sensitivity than previous all-sky monitors by an order of magnitude.
The observation has started in August 2009.
More detailed information on MAXI can be found in the MAXI homepage at RIKEN,
which produces and archives high-level data products such as images and light-curves for public release.

Daily event data are archived and released from DARTS, as well as data analysis tools
and calibration files (See Data page).

Note on the beta-release (2017-10-02)

DARTS and HEASARC are closely working together
toward the goal to release the MAXI event data from HEASARC simultaneously.
Also we plan to release the MAXI analysis tools and calibration files
in the official HEASoft
and CALDB from HEASARC, respectively.
Thus, please consider the current release (2017-10-02) as a beta-release.
When MAXI tools and calibration files are included in HEASoft and CALDB,
we will discontinue the tool and calibration-file release from DARTS.
We will continuously release the MAXI event data from DARTS as well as HEASARC.
